JOHN F. LIEB, OF PHILADELPHIA, PENNSYLVANIA.

AUTOMOBILE-TIRE.

T 0 all whom it may concern:

Be it known that I, J GEN F. LIEB, a citizen of the United States,residing at Philadelphia, in the county of Philadelphia and State ofPennsylvania, have invented certain new and useful Improvements inAutomobile-Tires, of which the following is a specification, referencebeing had to the accompanying drawings.

My invention relates to new and useful improvements in automobile tiresand more particularly to a spring tire for any design of vehicle, andhas for its object to dispense with the inner tubes now used in tires,thereby preventing blowouts and punctures of the inner tube, and alsogreatly lengthening the life of mileage of tires as well as take up thears and shocks caused by rough roads.

Another object resides in novel means for securing the tire to the rimof the wheel.

A further object of my invention is to produce a tire of this character,which will possess advantages in points of efiieiency, durability, isinexpensive of manufacture, at the same time being extremely simple inconstruction.

With the foregoing and other objects in view the invention consists inthe novel arrangement and combination of parts here inafter described,pointed out in the claim and shown in the accompanying drawings in whichFigure 1 is a transverse sectional view through my improved tire. Fig. 2is a de tail view of the spring used therein, and Figs. 8 and 4 aredetail perspective views of the clenching member and the double actingnut.

Referring more particularly to the drawings 1 indicates the tire orcasing having an inner shoe 2 placed therein to help preserve the shapeof and protect the casing 1. Disposed in the tire and having one endsecured to the shoe 2 by means of a clip 3 is a heavy coil spring 4, theother end of said coil spring extending upwardly forming an uprightportion 5, and provided with the left hand threads 5, the ends of thespring are to terminate at opposite sides of the coils.

In securing the tire to the rim of the wheel a clamping member 6 isemployed, said member comprising a stem 7, having a central opening 7therein and provided Specification of Letters Patent.

Application filed February 6, 1911.

Patented Mar. 12, 1912.

Serial No. 606,966.

with the right hand threads 8 and a base portion 9 provided withoutwardly and downwardly projecting flanges 10. A double acting nut 11is provided having a circular portion 12 provided with interior righthand threads to engage the threads 8 of the stem 7, the other end of thenut is rectangular and provided with interior left hand threads 14:adapted to engage the threads 5' of the upper end 5 ,of the spring.

In securing the tire to the rim the metal shoe is first placed in theouter rubber tire, the spring is then placed in the tire and its endsecured down by the clip 3, the clamp is then slipped down over the end5 and placed in position in the tire, the rim is then placed inposition, said rim is provided with openings through which the stem 7 ofthe clamp 6 is drawn, the double acting nut is screwed down on the upperend 5 of the spring, the stem 7 is then brought up to engage in thelower end of the nut and as the nut 11 is turned it will tend to drawupward on the clamping member thus clamping the tire securely to thewheel and making a cushion effect. The double acting nut 11 not onlyserves to hold the spring 4 in positlon but securely clamps the tire tothe casing through the stem 7 and the clamp 6, thus forming a verysimple and effective means for fastening the casing to the tire.

The outer casing 1 is provided with a plurality of openings in which arerigidly secured the copper eyelets 15 into which are forced the steelspikes 16, said spikes being held in place by the metal shoe 3, saidshoe being held in place by means of the spring 4:.

While I have shown and described the preferred form of my invention itwill be obvious that various changes in the details of construction andin the proportions may be resorted to for successfully carrying theinvention into practice without sacrificing any of the novel features ordeparting from the scope thereof.

Having thus described the invention what is claimed is:

In a spring tire, the combination of a casing having a metal shoedisposed therein, a coil spring arranged in the casing hav ing one endsecured to the shoe, the other end extending upwardly and provided withleft hand screw threads, a clampingmember slidably mounted on saidupwardly extending end, said clamping member comprising & hollow stemhaving right hand threads formed on its exterior, a, base for said stem,outwardly and downwardly ex Wardly ext-ending end of the spring to clampthe tire securely to the rim.
